From 1959-1961,the Desert Control Group of Academia Sinica Was established and a great number of scientists were organized to make comprehensive, surveys concerning the geomorphology, climate, hydrology, soil, vegetaiton and social-economic problems in main deserts in China,Taklimakan Desert is one of that,by the headquarter of Academia Sinica,Meanwhile , six intergrated experimental stations and more than ten central stations were established in five provinces in the Northwest China and Inner Mongolia. A network on desert studies and experi-ments was initially formed in desert areas in the Northern China.1962-1966, some typical studies were started to conduct in the fixed and semifixed positons. Since 1977, desert studies in the Institute w,ere Put into a new stage, namely, the Problem of desertification is regarded as an important aspect on desert research in China, and the characteristics, the processes and the developmental trends of desertification and its Prevention arc initiated to be conducted; the rational development and utilization of agricultural resourees in desert areas and the environment changes under the destruction of ecosystem are the key programmes during the stage. Desertology, a new developing sciences, is gradually coming to be developed in meetng of the needs of national economic development on the basis of the theoretical systems of geography, agriculture, forestry, animal husbandry and biology under the up-to-date theoretical guidances of the svstematization and the ecology.

1959—1961年中国科学院成立治沙队,组织了科技工作者对我国塔克拉玛干等大沙漠地区的地貌、气候、水文、土壤、植被、社会经济进行了综合考察,在这期限,内蒙及西北五省(区)建立了6个综合试验站,数十个中心站,初步形成了我国北方沙区科研试验網。1962—1966年,沙漠研究开始进行定位与半定位的一些专题性研究。1977年以后,沙漠研究进入了新的发展阶段,沙漠化问题列为我国沙漠研究的重要内容,开始研究我国沙漠与沙漠化土地的特征、演变过程、发展趋势及其防治;沙区农业资源开发利用与环境变化为重点课题。一门新兴学科——沙漠学在结合国民经济发展的需要中,在原有地理学,农、林、牧、生物学的理论体系的基础上,接受当前系统学和生态学的理论指导,正在逐步发展。
